Yeah, I’d like to know more too! It’s running linux, it seems. Maybe a RasPi or similar with an RTL-SDR dongle? It looks like there is stuff plugged in behind the display. I’d be interested in knowing more about the display as well.

Yup, I followed that tutorial (http://www.oz9aec.net/index.php/beaglebone/480-rtlizer). The nifty thing is rtl-sdr and rtlizer also run on my Ubuntu laptop and rtlizer accepts window size as a command line arg. I also got it compiled and running on BeagleBone Black and displayed on TV via HDMI. However, the LCD cape’s button don’t yet work in the Linux 3.8 kernel in my experience, so I was using the original white Bone with the 3.2 kernel.

Small correction: Propeddle is a software-defined 6502 computer (not “processor”).

It uses a real 65C02 processor, real RAM memory and a Parallax Propeller microcontroller. The Propeller creates a “virtual computer” around the 65C02. It should be possible to use this system to recreate many early 6502 based systems from the late 1970s and early 1980s, or create your own.

My target audience is those people who want to revive the time when hobbyists built their own computers, each one of them unique, and not necessarily with a specific purpose in mind. It also aims at teachers and students who are interested in what it’s like to know and understand a computer from the inside out and from the bottom up.

In the near future, I will make it available as a kit, but I need to finish the software and redesign the circuit board first.

PS some of the ideas behind Propeddle were used in the upcoming Ohio Scientific Superboard 600 (aka OSI Challenger) replica from brielcomputers.com: Check it out here.
